Application filed December 29, 1911. Serial No. 668,442.

T0 alt ywhom 'it may concern Be it known that I, GARRETP H. I-IUisrNG, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Loose-Leaf Devices, of which the following is the specification.

My invention relates to that class of devices which are designed to elevate a card or group of cards above the normal position of the remaining cards. Devices of this character with which I am familiar are subject to numerous objections.

My invention has for its object to overcome these objections by providing an improved construction where needed, for example, in devices of this class in which the rising bar is elevated by means of toggles and are provided with rollers on the ends of the rising bars for the purpose of overcoming the friction caused by pressure upon the indicating key or button are subject to the objection that while this accomplishes the result sought it makes it very easy for the bars to nuove laterally as they are elevated, this result being materially assisted by the unequal, insufficient or inadequate spring pressure provided. The result of this is that when the pressure upon the key is released the bar instead of falling into place strikes upon the. next adjacent bar on one side or the other and in order to get it into its proper place it is frequently necessary to remove all of the cards from the box. I have designed means for overcoming this objection, which consists of providing guides in which the rollers run. Another objectionable feature is due to the difficulty of returning the bars to their normal position. Various spring and gravity devices have been employed for this purpose all of which are subject to one or more objections. I have produced a means of applying spring pressureto the bars in such a manner as to insure. their positive return to position in every instance, and my device will produce an even and equal pressure upon the rising bar whether it is in the center or extreme edge of the card index box. Practice has shown that in devices of this kind it is necessary to provide some sort of a cushion along the inner walls of the sides of the box. Spring-pressed plates and felt cushions have been employed for this purpose.

My invention has for its further object to provide a new and improved form for securing the felt cushion in the box so that 1t can be quickly and easily. replaced when worn.

My invention also has for its further object to provide a new form for the keyboard of the machine so that all of the characters.

upon .the keys shall be visible at a glance.

My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

Figure l is a vertical section of a looseleaf card index box, fitted with my improvement. Fig. 2 is a top or plan view of the same, with the cover omitted. Fig. 3 is a cross section taken on the line m a; in Fig. l. Figs. 4 and 5 are detail views ,of the guide for the rollers on the rising bars. Fig. is a detail view of the means for securing the felt. Fig. 7 is a cross section taken on the line A A. Fig. 8 is a detail view in cross section of the felt and retainer. Fig. 9 illustrates a perspective view of one end of the frame; Fig.'10 illustrates a plan view of one end of the frame with one end of the front wall secured thereto.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, 1 is the box or containing case having a plurality of cards y 2 fitted therein, the cards 2 being omitted in some views for the sake of clearness. These cards are provided with pins (not shown) which are detachably secured thereto and are adapted to be engaged by the rising bars on their upward movement.

3 is the longitudinally movable bar, the upper end 4 of which is secured-to a pin 7 upon the outer end of which is mounted an indicator button or key 8.

9 and 10 indicate toggles by means of which the longitudinally movable bars are operatively connected to the rising bar l1. Rollers 12 are mounted in they ends of the rising bars 1I and run in grooves 14 formed in the guide 13. As more clearly seen in the i insuring the vertical travel of the roller 12 and preventing the possibility of any lateral movement of the latter. The rising bars and the longitudinally movable bars are located in the bottom of the box andv surrounded by a frame 16, the sides `of which form shoulders upon which the outer edges of the cards 2 rest. The front wall .17 of the frame is detachably secured to the frame and to the walls of the box. This wall 17 serves to prevent the cards 2 from being placed far enough forward in the box to interfere'with the inward movement of the pin 7. It is made detachable to permit of the ready removal or insertion of the bars for the purpose of assembling or repair, its lower part being mounted in slots 50 formed in the sides of the frame 16 and it has lugs 51 at its upper part which are secured to the box by means of screws 52 or any other -convenient form of fastening.

On the side walls 18 and 19 are mounted strips 20 and 21, which are formed with recesses intermediate their adjacent edges and the wall of the box. In this recess is mounted a plate 22 formed of suitable material, the sides 23 of which are folded upon themselves. A strip of felt 24 of' the desired thickness is mounted upon the said plate, the edges of the felt being secured to the plate by being compressed between the folded edges 23 and the plate 22. This plate is then slipped into the recess between the side walls of the box and the strip 21. 4,The strip 20 is then placed in position so that its lower edge engages the edge 23 of the plate 22. The strip 20 is then secured to the wall of the box preferably by means of screws 25, although it is obvious that any convenient form of fastening may be employed for this purpose.

A good deal of trouble has been found in holding the pins 7 in perfect alinement, owing to the fact that they are usually mounted in the front wall of the box .1 or they are mounted in bearings which are in turn mounted on the front wall of the box, which being made of wood affords but an insufficient hold. The result of this construction is that when the box has been in use for a short period of time, the bearings loosen and the pins get out of alinement, e

materially increasing the friction required to operate the device. I have avoided this objection by providing a metal plate 26, which is ixedly mounted upon the front wall of the box 1, in which are journaled the pins 7. A similar plate 27 of metal is secured to the inner side of the front wall of the box and the pins 7 are slidably mounted in these two plates. This insures their remaining in perfect alinement at all times. The keys are arranged in three rows,

the'upper I'ow being the shortest, each suc-l 46 which has two upwardly extending stems'l I 28 and 29 which are slidably mounted in a frame formed of four members, upper and lower bars 37 and 30, and side rods 35 and 36, which connect the upper and lower bars to each other at their outer ends.

The top bar of the frame is provided with a lug 41 which may be cast or formed on the bar 37 and provides a fastening by which to secure the frame to the end wall of the box, screws 40 which pass through suitable openings in the lug 41, serving to accomplish this result. v

The inward movement of the longitudinally movable bar 3 serves to start the rising bar 11 on its upward movement when it is brought into contact with the bar 46, which resists its further elevation by reason of the fact that the upwardly extending stems 28 and 29 which are slidably mounted in bear-y ings 38 and 39 formed in the bars 30 and 37 which have mounted thereon coil springs 44 and 45, a tension being( provided on the spring by means of washers 33 and 34 which are secured to the stems 28 and 29, the.

which is secured to the center portion of the bar 30 and depends therefrom, and is adapted to engage the bars 46 in its upward movement, but is so arranged so as to be out of contact at the time when the said bar starts its upward movement. This construction permits the bar 46 to start its upward motion easily, but the pressure increases as it is raised so that when released by the user it will be forcibly pressed back into position.

The mounting of the two stems 28 and 29 in the bars 30 and 37 insures constant alinement of the bar 46 and provides for an even pressure upon the rising bar whether the bar which elevates the bar 46 strikes it at the ends o1' the center.

Having described my invention, what I regard as new and desire to secure by Letters Patent, is:

1. In a device of the character described,
